Medical Technology The hemoglobin is the part of the erythrocyte that actually carries the oxygen and carbon dioxide. Red blood cells are made in the red marrow of bones, and live about 120 days. Because they wear out so quickly, an entire supply of red blood cells is renewed every four months. As red blood cells wear out in the bloodstream, they are taken in by the spleen, an organ on the left side of the abdomen below the stomach, and destroyed. Parts of the old cells are salvaged to make new red blood cells. The picture below shows what a blood smear looks like under a microscope.

How many skin cells do you shed every day? It takes roughly one month for new cells to get all the way to the top layer, meaning the skin you have a month from today will be completely new compared to the skin you have now. If you're wondering exactly how many skin cells fall off, get ready for some staggering numbers. Scientists estimate that the human body is made up of around 10 trillion cells in total. Your skin makes up about 16 percent of your body weight, which means you have roughly 1.6 trillion skin cells [source: BBC ]. Of course, this estimate can vary tremendously according to a person's size.

How long does it take for most of the atoms in your body to be replaced by others? In about a year every atom in your body would have been exchanged. Not a single atom in your body resides there forever and there is a 100% chance that 1000s of other humans through history held some of the same atoms that you currently hold in your body. To be sure this data is confounding and seems to defy logic.

Platelet (apheresis) donors may donate more frequently -- as often as once every seven days and up to 24 times per year. This is because the body replenishes platelets and plasma more quickly than red cells. Platelets will return to normal levels within about 72 hours of donating.
